As a demonstrator for technologies for the next generation of ocean color sensors,
the Hyperspectral Imager for the Coastal Ocean (HICO) provides enhanced spatial and
spectral resolution that is required to understand optically complex aquatic environments. In
this study we apply HICO, along with satellite remote sensing and in situ...

Current ocean color sensors, for example SeaWiFS and MODIS, are well suited for sampling the open ocean. However,
coastal environments are spatially and optically more complex and require more frequent sampling and higher spatial
resolution sensors with additional spectral channels. We have conducted experiments with data from Hyperion and
airborne...
This study uses derivative spectroscopy to assess qualitative and quantitative information regarding seafloor types that can be extracted from hyperspectral remote sensing reflectance signals. Carbonate sediments with variable concentrations of microbial pigments were used as a model system. Reflectance signals measured directly over sediment bottoms were compared with remotely sensed...
Remote-sensing reflectance is easier to interpret for the open ocean than for coastal regions because the optical signals are highly coupled to the phytoplankton (e.g., chlorophyll) concentrations. For estuarine or coastal waters, variable terrigenous colored dissolved organic matter (CDOM), suspended sediments, and bottom reflectance, all factors that do not covary...
The propagation of downwelling irradiance at wavelength l from surface to a depth (z) in the ocean is governed by the diffuse attenuation coefficient, K𝒹(λ). There are two standard methods for the derivation of K𝒹(λ) in remote sensing, which both are based on empirical relationships involving the blue-to-green ratio of...
A drifter equipped with bio-optical sensors and an automated water sampler was deployed in the California Current as part of the coastal transition zone program to study the biological, chemical, and physical dynamics of the meandering filaments. During deployments in 1987 and 1988, measurements were made of fluorescence, downwelling irradiance,...

Sensor design and mission planning for satellite ocean color measurements requires careful consideration of the signal dynamic range and sensitivity (specifically here signal-to-noise ratio or SNR) so that small changes of ocean properties (e.g., surface chlorophyll-a concentrations or Chl) can be quantified while most measurements are not saturated. Past and...
